V-Ray: SketchUp error with Expected string but no NilClass

Hi, I am new here and in Sketchup
Recently I instaled vray trial version in my computer, and it works for some files, but I starded doing this apartment interiors and it appears this error, I tried to install ruby console plugin and dynamic components plugin, bujt it still doesn´t work.
Someone can help me?

The error is " Something went wrong trying to initialize the sketchup model.
Expected String but no NilClass
C:\Program Files/Chaos Group/V-Ray/V-Ray for Sketchup/extension/ruby/live_scene:456:in `

I had the same problem, but just copy all geometry from your SU file to another one and use V-ray.

The same problem occurs in my model sometimes. Copy and paste to new file help, but after some time a problem is back on.

I already made it, but it occurs again and again, I’ve tried to cleanup, purge all and divide the project. But I had to divide till the project get smaller.

This is an issue you should report on the Chaos Group forums.

In my case, when I have this error it’s related to section planes. Everytime this error comes up I just delete all section planes and the render starts with no problem.

Hope it helps.
